Geldof calls for G8 expansion

Sir Bob Geldof has said the G8 must expand its membership or "lose its relevance".

The musician-turned-campaigner was in Japan this week to lobby the leaders of the world's eight most wealthy nations.

"The decisions can't be made by eight people in a small room anymore because the rest of the world is developing and they need to contribute," he said.

"But they also need to decide. And so going forward to the UN, that's when I think a lot of real decisions will be made now and I think the G8 will either expand or will lose its relevance."
